They are strictly German speakers we are talking of not just from Germany but could be from Austria, East Prussia, Alsace, etc so a broad group.
Strange inversion though as Ex Fallschirmjager, Luftwaffe, Waffen SS and Heer people always told me to use the abbreviation for Nationalsozialistische Deutsche Arbeiterpartei to signal it was the past and modern Germans were not like that. Often corrected for calling those in WWII; Germans. Most modern Germans would rightly call me bad bunny if I said the Germans were responsible for the Holocaust.
I am confused and feel like somebody who has walked into a party in a suit when it is fancy dress. Maybe I should have read the invite.
